DollaTek Mini 2.0 Hi-fi Electronic Stereo Audio Assembled Amplifier Portable AMP 10W+10W 2 Channel Class-D DC 12V Digital Booster Amplifier Board Module for CD MP3 MP4 PC Speaker

I built it into a tiny plastic box, plugged-in a disused 12V 2A power adapter and it works perfectly with some half-decent speakers, as a PC sound system. It isn't hi-fi but it's perfectly good and cost less than £5!

Brilliant amplifier with a great sound,works really well with my ipod.

Didn't work.

Used it in an arcade cab, connected to a pair of Sony 2 way speakers and a Raspberry Pi, sounds great an plenty of volume

Now I used this amplifier for a purpose which I can't state here. Suffice to say, I'm not connecting it to speakers, haha. That being said, the amp does work well and provides a low-noise solid output to anything that you'd want to drive with them. The only slight niggle I have with them is that the chip they use should operate down to 7V, however this will simply only operate at 12V without any real variability, which is a pain if you're using it in a battery-powered application, but perhaps that's just me. Overall, a cheap and reliable amplifier for the price. Definitely good for some DIY car speakers, though maybe adding more of a heatsink would be necessary for anything more powerful.

Brilliant, I used these to wire up speakers recovered from tv's works very well really happy with them

Even with good quality cable management it hums quite a lot. Should have gone with something better. It's loud , just buzzed like heck

Why did you choose this product over others?: specification is just what i wanted and at a low price

Piccolo amplificatore stereo, anche a me è arrivato senza il ponticello per l'alimentazione (necessario), segnalo vivamente la recensione di Julio dalla Spagna: lo schema per collegare gli altoparlanti è sbagliato, ai due morsetti centrali dei 4 per gli altoparlanti collegare o i due positivi o i due negativi, il test si fa con gli altoparlanti vicini e l'uno verso l'altro; inoltre nella descrizione è specificato di usare 4 fili e non tre per collegare gli altoparlanti.

Dit is goed koopje.

Ger ett för sin storlek ett bra ljud! Passar bra att koppla högtalare till då den ger lite extra ljud. Bör dock ha en equalizer (mjukvarumässig) för att få bästa möjliga ljud.

Va genial, pero al principio tuve unas dudas y tal como alguien ha comentado, sonaba extraño y con falta de graves. He trabajado mucho en sonido y electrónica. Hay un simple error en el esquema de conexionado de altavoces. Pero es básico para la calidad de sonido. La indicacion del canal izquierdo (L). Esta al revés. Esta simpleza hace que mientras un altavoz mueve la membrana hacia el frente el otro lo hace al revés y esto anula los graves principalmente ademas de una sensacion de sonido no centrado. Haciendo unas pruebas detecte el error. Corregido, suena con calidad mas que decente para lo que tenemos entre manos. Y con los graves correctos. Si alguien tiene algun ruido. Ojo a la fuente que usais. Debe ser estabilizada y filtrada para sonido. Conectado con unos altavoces Denon que no usaba a la salida de un pequeño ampli portatil de guitarra con Bluetooth. Suena perfecto. Y mueve los atavoces con soltura. Espero os sirva de ayuda.
